NOTE:
When the floor washing is completed, remove the wet cleaning container and clean out the water tank. Remove the wet cleaning mop and clean it.

NOTES:
It is recommended to vacuum clean all floors at least three times before the first wet cleaning in order to prevent excessive accumulation and transfer of dust and dirt on the wet cleaning mop.
In order to prevent corrosion and damage to the appliance please do not use any detergents or disinfectants in the water tank.
Upon completion of wet cleaning remove the water tank, drain the remaining water and clean the wet cleaning mop to prevent the forming of mold and unpleasant odors.
Remove the wet cleaning container if there is no need for wet  cleaning.
The wet cleaning container is only designed for use on smooth  floors, as the mop can get caught on the carpet flooring and impede free movement of the vacuum cleaner.

3. Delete Device: Press «Delete Device» to remove the linked device from the current account.

RESET WI-FI SETTINGS

If your phone cannot connect to the vacuum cleaner because you have changed the router configuration, forgotten the password, etc., you can start the setup once again (see sections «Adding a Device» and «Adding a Device Via an Access Point»).

NOTE

• Before setting up the Wi-Fi connection ensure that the device is connecting to a 2.4 GHz Wi-Fi network.
• Ensure that the robot vacuum cleaner is fully charged.

WI-FI NETWORK

• Use the correct wireless network password.
• Do not use a VPN (virtual private network) or proxy server.
• The Wi-Fi router should support the 802.11b/g/n and lpv4 protocols.
• The router should have a frequency range 2.4 GHz or a dual bandwidth which includes the 2.4 GHz range. The robot vacuum cleaner does not support the 5 GHz frequency range.
• If the robot vacuum cleaner cannot connect to a dual bandwidth 2.4/5 GHz Wi-Fi network switch to 2.4 GHz in the Wi-Fi settings. You may switch back to default after setup is completed.
• When connecting to a hidden network please ensure that you have entered a correct —SSID network name (case sensitive) and connect to a 2.4 GHz wireless network.
• When using a wireless repeater ensure that the network name (SSID) and password are the same as the main network.
• Install a firewall and Wi-Fi router port so that the robot vacuum cleaner could connect to the application server.
• Network safety requirements: Use TKIP, PSK or AES/CCMP encrypted WPA and WPA2 type networks.

MAP MANAGEMENT

А. CREATING A ROOM MAP IN REAL TIME MODE
A real-time room map would help you to easily understand the cleaning route and the ambient situation. A floor area map will be generated after cleaning.
The map will be updated in real time mode after each cleaning in order to ensure optimal navigation.

В. CHANGING POSITION AND MAP RE-CREATION
When the robot vacuum cleaner and/or the charging base has been relocated or the surrounding environment significantly altered, the robot vacuum cleaner will try to establish locations and create a new map in accordance with the new surroundings.

1. If the remapping is successful the robot vacuum cleaner will resume cleaning.
2. Should remapping fail, the robot vacuum cleaner will recreate the map to ensure normal navigation for the new cleaning.
3. If the remapping fails and the original map has included data on a «virtual wall» (restricted area), then the robot vacuum cleaner will not resume cleaning to avoid crossing to the restricted area.

NOTE:
Ensure that the robot vacuum cleaner starts the cleaning from the charging base every time.
Do not move the robot vacuum cleaner too often during cleaning, if accidentally moved – return it to the initial position.
